In a short time pools will be full of people, including little and grown-up ones, that hope to be fresher getting away from the extreme warm condition in the city. But often, we underestimate these magic places.
We are so tired by the heat that, somehow, we are not focused anymore and we end up not taking care about the water quality.
Pools are not always very clean, despite the consistent filtering. Sometimes, also pools in wellness centres are dirty. In order to "clean" the water of the pool, especially when kids want to go there, you can throw tennis balls into water and wait for a few minutes.
When it's hot, people who enter the pool sweat a lot. So in the water, on the surface, a combination of sweat, body fat and sun cream is formed.
These stains float on the surface and so you don't really want to dive in.
In order for the water to be brilliant again, just put tennis balls in water. Their material is able to asborb the fat film and so water is definitely cleaner. For the thermal spring water, it just takes one or two balls. Instead for pools, it takes at least 3/5 tennis balls depending on the size of the infrastructure.
In order to use them again, all it takes is to put them in the washing machine and get them dry under the sun. If you found it interesting, keep following our page in order not to miss similar articles that you can share with friends on social networks.
